Trait BranchKey 

pub trait BranchKey:
    Send
    + Sync
    + 'static {
    // Required methods
    fn as_key(&self) -> &'static str;
    fn all_keys() -> &'static [&'static str];
}

A routing key for conditional branching.

Implementors are fieldless enums whose variants map 1-to-1 to the named branches in a route node. The builder uses all_keys to verify exhaustiveness at build time.

Required Methods

fn as_key(&self) -> &'static str

The string key corresponding to this variant.

fn all_keys() -> &'static [&'static str]

All possible keys for this type (one per variant).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
